Werfault.exe Application Error
on Windows

Hi, I have an issue I hope you could help me with. Sometimes, when I open a random app, I am shown an error "Werfault.exe - Application Error." Is there anything I could do to fix this?

Werfault.exe application error is not a critical issue but should be addressed sooner or later. In most of the cases, the issue arises as soon as users boot into Windows, although occasions, when users are shown the error when trying to launch apps, is not uncommon as well. Alternatively, Werfault.exe application error can show up at completely random times and not be associated with any actions performed on the PC.

First of all, we should clarify the related executable is a legitimate Windows component that belongs to the Windows Error Reporting service. It allows Microsoft to collect error-related technical data and send it off to internal servers. In return, users are then presented with options that could help them fix relevant issues. Besides, the service also allows Microsoft to analyze patterns, frequencies, and other data and help them resolve bugs[ref en-1] within the operating system.

If you received an error pop-up "werfault.exe – Application Error," it means that the culprit is not the werfault.exe file itself, but rather the application that you attempt launching. Typically, this error contains the following information:
